The world's most expensive footballer scored the first and made the second in a scintillating match that took Brazil into a last eight showdown with either Belgium or Japan.
The match had been billed as a duel between Neymar and Javier Hernandez, but the West Ham striker was more noticeable for his platinum-dyed blond hair, a choice also made by central defender Carlos Salcedo, before being replaced in the second half.
Neymar shrugged off accusations of "acting" after playing a starring role in Brazil's 2-0 World Cup last-16 win over Mexico.
The closest they came to scoring was a Hector Herrera chance which, according to the Infogol app, had just a 15% chance of finding the net.
Neymar's influence was clear in stats that showed that in Russian Federation he has attempted more shots and created more goalscoring chances than any other player. They caused problems for Brazil, too, initially.
Paulinho should have doubled that advantage in the 59th minute, but Ochoa was once again equal to his whipped strike from 12 yards, while the over-worked goalkeeper also tipped over Willian's powerful effort four minutes later.
Neymar certainly showed that edge at the Samara Arena on Monday. As Neymar lay on the ground with the ball trapped between his legs, Layun stepped on the Brazilian's ankle as he picked the ball up. Television pictures showed a slight brush on his ankle but his reaction seemed like he'd been run over by a auto. "It's obvious", Layun said.
"I think it's a shame for football".
"This should be a sport of ability, of determination, a game of men, not of so much clowning". Asked by a reporter that the replay showed a slight touch by Layun, Osorio responded: "I respect your opinion".
"A collective group's dream is over and I think that of the country as well", he said. It's your interpretation. I'm entitled to give my opinion.
"But the attacks on him by the foreign media and foreign fans frightens me. In the defensive situation, we were very solid", Willian said after the final whistle.
It was those stoppages that Osorio blamed for Mexico losing momentum. "At the top level this is a lot", he said.
Neymar, though, still led the celebrations, charging toward the corner flag. I will answer that question.
Brazil manager Tite believed Neymar was treated unfairly, stating: "I saw what happened. You can analyse the video".
"I don't much care for criticism or praise because this can influence a player's attitude".
"I just want to play and I help my team-mates, I have to help my team and that's what I am here for, nothing else". "Osorio has done handsome work and it's why this was a lovely match that excited me". For all the good attacks, Mexico lacked in finishing. Brazil aren't used to facing such opposition, opposition that comes at them so relentlessly as the Mexicans were coming. Vela and Lozano did extremely well to put pressure on Brazil from the wings. The only issue was with the final ball. They were creating all sorts of angles, they were making all sorts of runs with the ball and off it, trying to carve open Brazil.
What do you make of Neymar's behaviour? Instead of Neymar, it's been Coutino who has been Brazil's leading man at this World Cup but his passes were being cut, his shots at goal being blocked or sailing wide. Willlian's ball beat Mexican goalkeeper Guillermo Ochoa and Jesus, but not Neymar, who was there to score his team's first goal.
The plan was nearing ideal execution.
"But even then he managed to stand out, in the second half he shined technically".
